One of the trend that does not changed in automobile industry is improving manufacturability, reducing weight and cost savings. For that purpose, glass fiber reinforced polyamide has replaced metal as the material of choice for intake manifold in many vehicle brands. currently, PA66+GF35 and PA6+GF30 has being applied globally in intake manifold. gasoline engine of Hyundai motor company also, PA6+GF30~35 is being applied. Since Plastic material applied to intake manifold, it brought smoother surfaces, higher design freedom and lower unit cost. Since 2012, Hyundai Motor Company have been developing PP Plastic that could reduce weight and cost, while maintaining PA material property. Especially, this PP Plastic will be applied to Kappa 1.4 MPI intake manifold that is being developed by Kefico since 2015. Because PA Plastic has been used to manufacture the Intake Manifold, there are many guidelines for design and analysis(CAE). but, There are no guidelines for PP plastic because PP plastic does not used as a material of the Intake Manifold. Through this paper, We Suggest Intake Manifold design guidelines for PP plastic.
